Geographic coordinate system, Essay Example for Free

Geographic coordinate system, Essay Sextant- allowed users to determine their latitude to within a sea mile or two The gnomon or sun-shadow disk- operated like a sundial, enabling the user to determine his latitude by the length of the suns shadow cast on a disk floating level in water. The Arabian kamal- a rectangular plate that one moved closer or farther from ones face until the distance between the North star and the horizon exactly corresponded to the plates upper and lower edges. The distance the plate lay away from the face—measured by a string tied to the center of the plate and held at the other end to the tip of the nose—determined the latitude. cross staff Tools used to measure longitude (Lesson 02.01) (use the first resource in this lesson to help you) Be able to list and describe the 2 main tools used to measure longitude in early navigation the chronometer- the sextant to figure longitude using the lunar-distance method Current Navigation Tools (Lesson 02.01) What tool do we currently use to determine location (latitude and longitude)?

Comparing A Turn with the Sun and A Separate Peace :: comparison compare contrast essays

Essay Comparing A Turn with the Sun and A Separate Peace  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Although many similarities exist between A Turn with the Sun and A Separate Peace, both written by John Knowles, the works are more dissimilar than alike.   A Separate Peace is a novel about the struggle of a senior class in the face of World War II, and it focuses on two best friends, Gene Forrester and Phineas.   A Turn with the Sun is about a young man who struggles to fit in as a freshman in the closed microcosm of a senior dominated school who struggles, vainly, to make a name for himself.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Knowles wrote A Turn with the Sun in the third person.   His character, Lawrence is trying to make a name for himself as an underclassman.   He suffers from a poor self image, as "Lawrence sensed once again that he was helplessly sliding back, into the foggy social bottom-land where unacceptable first-year boys dwell." (A Turn with the Sun:12) He sees his achievements and failures as analogous to his worth as a person.  Ã‚   He feels that he is a failure, yet is thankful that, "...the hockey captain had never invaded his room, as he had Fruitcake Putsby's next door, and festooned his clothes through the hall; he had never found a mixture of sour cream and cereal in his bed at night, no one had ever poured ink into the tub while he was bathing.   The victims of such violations were genuine outcasts." (A Turn with the Sun: 12) The other boys see Lawrence as an annoyance rather than an exile, while he feels that he is better than the other boys at Devon. This is reinforced when he thinks, "When he plunged from the railing he had been just another of the unknown new boys, but when he broke the surface of the water in that remarkable dive, one that he had never attempted before and was never to repeat, he became for his schoolmates a boy to be considered."   (ATurn with the Sun:13) The dive serves as an inauguration into the school's social system.   It is symbolic of risk, achievement and imperfection; it brings together the gap between the river, which represents the unknown, and the bridge one stands on, the tangible world where the boys feel secure.   Lawrence, like Leper who will be discussed later, "...merely inhabited the nether world of the unregarded, where no one bothered him or bothered about him.

Causes of Imperialism

Causes of Imperialism In the nineteenth and twentieth centuries, imperialism- a force of a greater nation that controls a smaller, weaker nation- began to take over many parts of the world in a frenzy. The more dominant countries at the time, such as the United States and many European countries began extending their influence to areas all over the world, from the Phillipines (which would be 56. 5% controlled) to the Africa (which would be 90. 4% controlled) , because they felt their â€Å"nations' will to power† was the best. Document 3) England began showing signs of wanting to control other nations, because this meant that there would be more trade with other countries. Imperialism meant more trade with other countries, and more trade meant more money. The more money meant that the country had more money to invest in industrialization. Industrialization also meant that buyers and customers had to be found in which to sell their products- another benefit of imperialism. Last ly, raw materials could be obtained cheaply, as could cheap labor.Because the English were ? The machinerization of England's factories did not only change England's economy, it changed the world. They were the first in the entire world to experience things like materlialistic benefits, and social pricetags of industrialization. This had happened for several reasons. England had good transportation, an abundant labor supply, inventions that revolutionized the manufacturing of many products (mostly the textile industry), and a stable government. All of a sudden, factories were making hings so quickly, so efficiently, that more and more materials were needed. Although certain machines and inventions helped, it simply wasn't enough. There was a very big piece of the manufacturing process missing, a piece that would improve England's manufacturing even further. And that was the very concept of unlimited supplies. Supplies come at a very heavy price, so the idea of an unlimited source of supplies was a novel idea. The problem was where to get them from†¦ And imperialism was the answer.The ability to control country naturally weaker yet rich with resources was absolutely perfect, and important for the development of of the country. Africa was the perfect choice to begin with. It was rich in many natural resources such as gold, platinum, diamond, gas, oil, coal, water, and free labor which â€Å"lay ungarnered in Africa because the natives did not know their value. † (Document 1) ? The English also felt a moral obligation to help the natives, whom they saw as cannibals and infidels. The English felt that they were not only â€Å"unfit for elf-government† (Document 7) but also â€Å"degraded, ignorant, and swept by disease. † (Document 4) They would continue to look down on them, mistreat them, and use them as a labor force. They felt that they could not be left by themselves, and had no choice but to be ruled over by a higher force; in this case, the English. This is why the English ultimately ruled over Africa for so long. Overall, the English were the number one force of nationalism. This is due to industrialization and their strong sense of nationalism.

Design And Load Analysis Of Storage Bins - 1638 Words

[C.E.2.1] INTRODUCTION: Project Title : Design and Load Analysis of Storage Bins Using CREO 2.0 and CATIA V5 R18 Software. Duration of Project: March 2010 to May 2010 Organization : Swinburne University of Technology (SUT), Melbourne. Position : Team Leader Location : Industrial research institute, Swinburne University of technology, Melbourne, VIC, Australia [C.E.2.2] OVERVIEW: A project titled â€Å"Design and load analysis of storage bins using CREO 2.0 and CATIA V5 R18 software†. I carried out this project in order to fulfill the requirements for my first semester study during my Masters Degree. In this project a sheet metal component was designed and load analysis carried out using CATIA V5 R18. I selected a sheet metal storage bin†¦show more content†¦These results are from guidelines for the design and manufacturing department from Swinburne University of Technology. From this data designers could redesign or rework the component for better efficiency and better aesthetics. In this project I designed the component in CREO 2.0 and the model was then exported to an IGES format. The IGES file was then exported to CATIA V5 for further analysis. This helped me to determine the ideal combination of the part’s geometry design, material used, and ideal load conditions that would produce quality storage bins with the sheetmetal process. [C.E.2.4] ORGANIZATIONAL STRUCTURE This project was carried out at the Faculty of Engineering and Research, Swinburne University of Technology, Melbourne, Victoria, Australia. I was guided by the CAD/CAM laboratory faculty at the University for this Project. The organization structure of the project is as follows: Prof. Syed Masood (Course Coordinator, Faculty of Engineering and Industrial Sciences) Prof. Romesh (Project Supervisor) Tim Barry (Research Fellow, Laboratory In Charge) SaiNarasimha Rao Maddali (Team Leader) Sajjie c.Joseph (Team Member) [C.E.2.5] COURSE OF ACTION: In this project I designed a sheetmetal component and static and thermal analysis using CATIA V5 was performed. The component selected for this project was a Sheet Metal storage bin. The steps carried out
